tio-n within reasonable limits and held in an operative position without marring the appearance of the projection to which it is attached and without inconvenience on thc part of the operator.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are 'employed to designate corresponding parts throughout the several views,

Figure 1 is a perspective of the improved portable work bench, and

Figure 2 is a fragmentary plan view of the same.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 designates a suitably stout bar having a series of apertures 6 for the reception of fastening pins to be described,

Nith reference to Figure 1 it will be observed that a jaw 7 is provided intermediate the ends thereof with an opening receiving the bar 6 and a pin 8 may be extended through the jaw 7 and one of the openings 6 so as to securely hold the jaw in a fixed position. An arm 10 is also mounted on the bar 5 and is provided with a pin 11 by means of which the arm. may be adjustably secured to the bar 5. The outer portion of the arm 10 is provided with a feed screw 12 having its forward end provided with a disc-shaped j aw 1a adapted to co-operate with the jaw 7 in engaging a door jamb 15 or any other convenient projection. The feed screw 12 is, of course, threaded through one end portion of the arm` 1() and when the feed screw is advanced the head is urged flatly int-o engagement with the object l5 which may be a projection of any nature. Of course, the disc-shaped head 111 is swiv elled on the feed screw 12 so that the head will not be turned when the feed screw is advanced. T he rear portion of the feed screw 12 is provided with a handle 16 by means of which the feed screw may be operated.

' One end of the bar 5 may be provided with a supporting member 2O secured in an adjusted position on the bar by means of a pin 21. The pin 21 may be extended thii'ough any one of the openings 6 and, therefore, holdsl the supporting member 20 in an adjusted position on the bar 5.

The other end of the bar 5 carries a sec- Y ond supporting member 22 held in an adjusted position by means of a pin 253 and it will be seen that the plank or other work support 25 may be mounted on the transverse supportingmembers 2O and 22 and will rest against the projection 15 and against. a transverse shoulder or projection 24- on the upper side of the member 20. Also fastening members 26 of any suitable type may be employed to connectthe work supporting plank to the members 7 and 10 or to any other convenient part of the framework.

In carrying out vthe invention the projection 241on the upper side of the transversely extending member 22 forms a stationary j aw which co-operates with a movable jaw' 26. The movable jaw 26 is movable on theupper surface of the member 22 and is co-ntrolled by means of a feed screw 27. A handle 28 is connected to the rear end of the feed screw'27 and forms a means whereby the movable jaw' 26 may be adjusted. The feed screw is threaded through a projection 30 on the termina-l portion of the transversely extending member 22. `With reference to Fig. 1 it will be seen that the jaws V2Liand 26 cooperate in the formation of a vise adapted for engaging pipe, wood, or any other material.

Suitable legs 35 may be employed to support the frame work and in this respect effectively cooperate with the members 7 and 111. Y

lli/*ith reference to the foregoing description tcaken in connection with the accompanying drawing` it will be seen that the improved portable work bench may be applied to any convenient projection either in a house or a work shop or in the open with out marring the appearance of the projection to which it is connected and Without inconvenience or the exercise of unusual skill.

Having thus described Vthe invention what I claim is:

l. A portable Worx bench comprising a .main bar, a jaw adjustably sec red on the main bar, an arm adjustably secured 'to said bar land having a threaded opening, a feed screw threaded through said opening and having ra swivelly mounted head adapted to co-operate with said jaw fin engaging a projection, supporting members mounted on said bar adjacent the ends of the same, and a Work-supporting plank Ymounted on said supporting members.

2. A yportable Work bench comprising a main bar, a jaw adjustably secured on the main vbar and projecting from lopposite sides of the saine, an arm -adjustably secured to said bar and having threaded opening, a feed scren7 threaded through said opening and having a swivelly mounted headadapted to co-operate with said jaw in engaging a projection, supporting members mounted on said bar adjacent the ends of the same, a Work-supporting `plank mounted on said supporting' members, and means to secure said plank on said supporting members.

8. A portable Work bench comprising` a lnain bar, a `jaw adjustably secured on the nain bar .and projecting from opposite sides of. the same, an arm adjustably secured to said bar and Vhaving a threaded opening, a feed screw threaded `through said opening and having a swivelly mounted head adapted to co-operate with said jaw in engaging a projection, supporting members mounted on said bar adjacent the ends of the same, a Work-supporting plank mounted on said supporting niiembers, means to secure said plank to said supporting members, and legs co-opera'ting `with said jaws in supporting the bench.

4. A portable Work bench comprising a main bar, a jaw adjustably secured on the main bar and projecting from opposite sides of the same, an arm adjustably secured to said bar and having a threaded opening, a

feed Vscrew threaded through said opening and having la sivivelly mounted head adapted to co-operate with said jaw in engaging a projection, transversely extending supportA ing members mounted on said bar adjacent the ends of the same, a Worlcsupporting plank mounted on said transversely extend ing members, means to secure said plank on said transversely extending members, legs co-operating vwith said jaws in supporting the bench,` one of said Vtransversely extending members being provided With an upstanding kcombined shoulder and jaw, a second jaw mounted on Asaid transversely eX- tending member adjacent said combined shoulder and jaw, and a second i'ieed screw connected to said s condnanied janT for positioning the same.

5. A portable Work bench comprising a main bar, -a jaw adjustably secured on the main bar and projecting from opposite sides Vot' the same, Aan arm adjustably secured to said bar and having a threaded opening, a feed screvvv threaded through said opening and having asWivelly mounted head adapted to co-operate With saidjaw Iin engaging a projection, transversely7 extending supporting members mounted on said bar adjacent the ends of the saine, a work-supporting plank mou on said transversely extending members, means 'to secure said plank on said transversely extendingr members, legs co-operating With said jawsy in supporting the bench, one of said transversely entending members being provided with an upstandingcombined shoulder and jaW, a second jaw inountedon said transversely eX- tending member adjacent said combined shoulder andjaw, a vsecond feed screw connected to said second-named jaw lfor positioning the same, one :edge of said lplank being engaged With said combined shoulder and jaw.
